[Winpcap-users] pcap_findalldevs_ex'

[Gianluca Varenni]

Hi.

WinPcap can list the adapters on a remote machine (and capture from those remote adapters) *only* if the remote machine has WinPcap installed *and* the remote capture daemon has been started.

Alternatively, you can also use the remote capture daemon on a UNIX machine, recompiling the libpcap version shipped with WinPcap under that OS.

The instructions to use the remote capture daemon are here:

http://www.winpcap.org/docs/docs31/html/group__remote.html

If the remote hardware is not running WinPcap (or the patched libpcap), then there's no way to list/capture from remote adapters using the remote protocol used by winpcap.

Hope it helps
GV

    Hi.

    pcap_findalldevs_ex lists remote adapters (using the "rpcap://..." string) *if* you have WinPcap remote capture daemon installed and started on the remote system. I think that the service you have on port 5060 of the remote machine is some service you developed, not the remote capture daemon, isn't it?

    Have a nice day
    GV

      Good Morning.

      I want to send some packets to a remote adapter connected to my PC.
      I want to retrive its name to pass to the function 'pcap_open'.
      So I want to have the list of the remote adapters connected, but I have some problem using the function 'pcap_findalldevs_ex'.

      My PC addressed 10.0.0.11 is connected to a host addressed 10.0.0.12 that offers a service on port 5060.

      This is the code:

      /* Retrieve the device list from the remote machine */
      if (pcap_findalldevs_ex("rpcap://10.0.0.12/5060", NULL, &alldevs, errbuf) == -1)
      {
          fprintf(stderr,"Error in pcap_findalldevs_ex: %s\n", errbuf);
          exit(1);
      }

      This is the error message:

      "Error in pcap_findalldevs_ex: Is the server properly installed on 10.0.0.12?  connect() failed: Impossibile stabilire la connessione. Risposta non corretta della parte connessa dopo l'intervallo di tempo oppure mancata risposta dall'host collegato.  (code 10060)"

      Wath is the problem, please?

      Thank you
